I think it's more the technique used, more than the effect. My reason for this, being that there are many "effects" that can be done with various stacked decks (for example), but it's the stack itself which is "original".
Also, look at Twisted Aces. There are many versions of this, from the original Vernon effect, to the Asher Twist...
